Ash accumulation on the heating surface.
The scaling and ash deposition on the water-cooled wall of the furnace and the ash deposition of the superheater, convention tube bundles, economizer and preheater can increase the thermal resistance of the flue gas, weaken the heat transfer, lessen the cooling effect of the flue gas and increase the exhaust gas temperature of the gas-fired boiler.
Too high excess air coefficient.
Under normal circumstances, as the furnace outlet excess...
Power boilers take the chemical energy stored in fuel, convert it to heat energy in the combustion process, and transfer that heat energy to water to produce steam. The transfer of energy from combustion gases to the water and steam is called heat transfer.
In addition to quality, price is also an aspect that most corporate users are very concerned about when they purchase the gas-fired thermal oil heater, so what is the price of a set of high-quality gas-fired thermal oil heater?
1. The types and parameters of thermal oil heater, such as rated thermal power, rated working temperature, etc.
Rated thermal power: heat output per unit time. Thermal oil heaters with different heat output per unit time have different prices.
Rated wor...
There’s a lot to carefully consider when you’re upgrading or replacing your facility’s equipment. Thermal oils tolerate higher temperatures than water-based formulas without boiling or unduly increasing system pressure.
Thermal fluid heating, and thermal oil systems, in particular, have several advantages. These advantages include:
Efficient industrial heating is important for a variety of reasons – both within your facility and its daily operations, a...
How to select the right thermal fluid heater for your plant can be a tough task. With so many industrial heating equipment manufacturers and heater models on the market, it can be difficult to narrow down your options and make a decision.
It’s probably going to be tough to focus your full, uninterrupted attention on the task of choosing a new industrial thermal fluid heater for a long stretch of time. You’re going to need to make the best decision possible for your plant qui...
The heat requirements of the building materials manufacturing process are very varied. A steam boiler plays a key role in the process of creating building materials. For example, materials like molded brick rely very much on steam heat from an industrial steam boiler in order to pressurize and harden the elements that make up the brick. Without exposure to that kind of heat and pressure, these materials would be a loose construction of sediment, rather than dependable, solid building components....
In addition to water, other fluids can transport heat in industrial boilers, and thermal fluids usually replace water when higher temperatures are needed.
Shell boilers may be defined as those boilers in which the heat transfer surfaces are all contained within a steel shell. Shell boilers may also be referred to as "fire tube" or "smoke tube" boilers because the products of combustion pass through the boiler tubes, which in turn transfer heat to the surrounding boiler water.
